LTC3892MPFE-1#TRPBF

DC DC Switching Controllers Overview

The LTC3892MPFE-1#TRPBF is a high-performance dual step-down DC/DC switching regulator controller from Analog Devices Inc. It drives all N-channel synchronous power MOSFET stages to minimize power loss and noise through out-of-phase operation. The device supports an input voltage range of 4.5V to 60V. It features adjustable switching frequencies ranging from 105kHz to 835kHz for the first channel and 350kHz to 535kHz for the second channel. The output voltage is adjustable from 800mV to 59.4V, with a maximum output current capability of 25A per phase. It operates within a temperature range of -55°C to +150°C TJ.
